Abstract:
Refrigerant manufacturing challenges any on-line analyzer for rapidly speciating and quantifying reactants, intermediates, and products in the presence of hydrofluoric acid concentrations ranging from 5 to 80+ percent. For more than 3 years an AI-60 process NMR system has been providing such analyses at several reactor stages.
This presentation will highlight applying on-line 19F spectral acquisition and analyses on gas phase samples. NMR hardware configuration needed to safely analyze high HF concentration fluids (liquids or gases) as well NMR’s nuclei selectivity (hydrogen, fluorine, phosphorus) which enables 19F NMR to achieve significant improvements in speciation and quantitation accuracy will be presented.
